Answer:
Angle 2: 45
Angle 3: 45
Angle 4: 135
Angle 5: 135
Angle 6: 45
Angle 7: 45
Angle 8: 135
Step-by-step explanation:
Angle 1 and 2 are supplementary meaning the angles add to 180 degrees.
180-135=45
4 is opposite of 1, so it is the same value (it is also supplementary to angle 2)
3 is opposite 2 and supplementary to 1, so it is 45 as well.
5 is the same as 1 because it is made from the same line crossing a parallel line to the one angle 1 is formed from (sorry that sounds confusing)
6,7,8 are found the same way as 2,3,4, and 5.
